  • 사출금형 공정계획이란 금형설계를 완료한 후에 설계된 금형을 경제적, 효율적으로 생산하기 위하여 수행해야 할 제조공정에 대한 계획이다. 이러한 공정계획은 전문가의 경험에 의존함은 물론 많은 시간이 소요된다. 그리고 사출금형 공정계획은 현장경험을 토대로 완전 수작업에 의존하고 있으므로 공정계획전문가의 경험과 숙련 등에 따른 변동, 공정설계용 데이터의 부정확 등에 의한 공정계획 그 자체가 갖고 있는 부정확도에 따라 많은 문제점이 있다. 이러한 문제점과 함께 공정계획 전문가의 부족현상, CAD/CAM시스템의 보급 및 생산형태의 다품종소량화 현상에 따라 공정계획의 자동화가 필요하게 되었다. 본 논문에서는 사출금형 공정계획을 자동화하기 위해 사례기반추론(Case Based Reasoning)을 이용하였다. 사출금형의 공정계획은 성형품의 종류에 따라 다양하고 복잡하기 때문에 지식으로서 접근하는데는 한계가 있었다 그래서 본 논문에서는 전문가들의 경험지식을 이용한 사례기반추론을 이용한 공정계획시스템인 IIMPPS(Intelligent Injection Mold Process Planning System)를 개발하였다. 사례기반추론 공정계획 시스템을 개발하기 위해 과거 공정계획을 적합한 사례로서 표현 및 구성하고, 적절한 공정계획을 수립하기 위한 사례의 검색 및 조정방법을 제안하였다. 본 시스템은 차후에 가상생산 에이전트(최형림 등, 2000) 중에서 공정계획 에이전트의 엔진으로서 역할을 수행할 것이다.

  • 우리나라 기업 창업 후 5년까지 생존율(27.5%)은 OECD 평균 생존율(43.9%)보다 낮으며 최근 5년간('11~'15년) 연평균 창업은 81만개, 폐업은 70만개로 다산다사(多産多死) 특징 보유하고 있다. 사업 실패로 인한 폐업은 개인적인 차원을 넘어 사회적인 문제로 확대되고 국가 경제에 부담으로 작용하고 있다. 이에 본 연구에서는 사업실패경험이 학습효과와 자산으로 승화하여 재창업의지에 직접적인 영향을 미치는지, 사업실패자에 대한 사회적지지가 재창업 의지에 어느 정도 상승효과를 주는지에 대해 분석하기 위해 사업실패자자들을 대상으로 자료를 수집, 실증 분석하였다. 본 연구 결과는 첫째, 사업실패경험 속성중 비재무적 손실이 발생한 경우 재창업의지에 부(-)의 영향을 미치는 것으로 나타났다. 이는 비재무적 손실이 크다면 재창업의지는 낮아지게 된다. 둘째, 재무적 손실이 발생한 경우에는 재창업의지에 영향을 미치지 못하였다. 셋째, 조절변수인 정서적지지는 비재무적 손실이 발생한 경우 재창업의지에 정(+)영향을 미치는 것으로 나타났다. 따라서 재창업지원은 이들이 경험한 비재무적 손실을 회복 할 수 있도록 정서적지지를 활용하는 다양한 정책안들이 고안 되어야 하고 사업실패로 재무적 손실이 크게 나기 전에 사업을 빠른 시일 내에 정리토록 하는 것이 재도전 시책에서 무엇보다 중요하다는 시사점을 주고 있다.

  • 2015년 기업생멸 행정통계에 따르면, 우리나라의 최근 5년 동안('2010~2014년) 연평균 창업은 77만개, 폐업은 69만개인 것으로 나타났다. 지난 2015년 한해에만 개인사업자로 106만8313명이 창업을 하고 73만9420명이 폐업을 했다. 이는 하루 평균 3000명이 창업을 하고 2000명이 문을 닫는 셈이다. 실패를 경험한 기업인들은 여러 가지 심리적, 경제적 어려움에 직면하게 된다고 연구 보고되고 있다. 이같은 결과는 사업실패를 경험한 기업인들에 대한 케어의 필요성을 보여준다. 지난 2010년부터 정부가 실패기업인들에 대한 재기지원사업에 나서고는 있으나 재창업지원제도의 효과성에 대해서는 보장하기 어려운 상태다. 일각에서는 재창업지원이 양적인면에서는 활성화됐으나 질적으로는 아직 미흡하다고 지적이 나오고 있다. 이같은 상황에 착안하여 본 연구는 사업실패를 경험한 기업인들이 겪게되는 심리적 특성과 재기를 하고자 할 때 방해요소로 작용하는 감정요인에 초점을 맞추고자 한다. 따라서 선행연구를 통해 사업실패를 경험한 기업인들의 감정메카니즘을 규명한 모델(건강신념 모델:Health Belief Model)을 적용한 창업실패관련 개인평가와 사업실패경험(재무적 손실, 비재무적 손실)이 재창업의도에 어떠한 영향을 미치는지 규명하고자 한다. 감정요인인 창업실패관련 개인평가는 지각된 심각성, 지각된 취약성, 지각된 장애로 구성했다. 또 창업실패관련 개인평가와 재창업의도 사이, 사업실패경험과 재창업의도 사이에 재창업지원정책, 창업자기효능감이 각각 조절작용을 하는지 유의미한 관계성을 알아보고자한다. 연구 대상은 정부 재창업지원 프로그램을 진행하고 있는 중소기업진흥공단, 서울산업진흥원, 재도전지원센터등 기관의 재창업지원을 받은 기업인을 대상으로 설문을 실시하여 이들이 재창업지원서비스를 받기 전과 후에 대한 측정을 통해 실증분석을 하려고 한다.이 연구가 설정한 가설이 맞을 경우, 시사점으로는 정부의 재창업지원 프로그램의 효과성에 대한 검증이 될 것이다. 또 창업실패관련 감정메카니즘 규명으로 사업실패 기업인들의 재기를 도울 수 있는 재창업지원정책의 고도화가 가능해 질 것으로 판단된다.

  • The concern regarding inability to perform CPR properly was widespread, and few studies, however, have queried bystanders regarding their responses to an actual emergency. This study assessed how often CPR was performed by CPR-trained bystanders and what factors were associated with the performance and nonperformance of CPR by trained bystanders. From a 2,000 sample survey of the National Emergency Medical Center in Korea (2008), it extracted object persons who actually experienced an emergency situation, and examined closely the relationship of CPR education experience and CPR performance in an emergency. 169 completely interviewed, 23(13.6%) had CPR education experience and performed CPR in an actual emergency, 40(23.6%) had CPR education experience but didn't performed, 12 (7.1%) didn't have CPR education experience but performed, and 94(55.6%) neither had CPR education experience nor performed. Specifically, within bystanders who had CPR education experience, those who CPR was performed were different from those who CPR was not on medical emergency-related characteristics such as CPR knowledge(p=0.001), 1339 emergency phone number(p=0.006) and 1339 emergency services(p=0.001). Consequently, to consider social characteristics or an economic condition, various CPR teaching strategies should be prepared to continuously propel.

  • The period after the PhD has a huge impact on the careers of researcher from a researcher lifecycle perspective. This is a turning point which student receives guidance from professor and become an independent researcher. Furthermore, they learn to develop ideas for independent research, apply for grants and manage a project; they also form expert networks in related filed and publish papers to share their findings. This study focuses on the period between earning doctoral degree and being employed as a stable position in university. This study starts from a research questions that asks which factors of postdoctoral experience affect research output. In this study, the paper performance, especially co-authorship of paper, of postdoctoral researchers was investigated. The cumulative advantage theory and Matthew effect were employed to shed a light on this research question. The empirical work is based on the Survey & Analysis of National R&D program in Korea conducted by Korea Institute of S&T Evaluation and Planning (KISTEP). The correlations between the research output and characteristics of postdoctoral experience were verified. These results are expected to contribute as new empirical evidences on investigating knowledge transfer activities of new PhDs.

  • This research analyzes the economic attitude and economic literacy of college students that attended college or graduated within one year. The study measures diverse traits of economics, such as economic rationality, economic interest, risk aversion, and competitive spirit or selfishness. Results show that students enrolled in economics courses have an interest in economics, received high grades, and graduates have a relatively higher level of economic rationality. Second, students who have taken courses in economics showed a higher level of interest in economics. Thus, the correlation between such education and students' interest cannot be denied. Third, regardless of their experience in taking economics courses, the level of knowledge in economics is low for community college students. Although the rationality and interest of those students enrolled in economics courses are higher compared to students not enrolled in such courses, it does not play a pivotal role in enhancing their economic intelligence. This shows that the current education in economics positively influences an individual's economic traits but does not necessarily generate knowledge in economics. Education should focus more on associating essential economic concepts with real-world issues.

  • The purpose of this study was to examine the child-rearing difficulties of mothers with twins in an effort to discuss how to lend assistance to these mothers, as the birth of twins has been on the rise. The participants in this study were six mothers who resided in the city of P and raised infant twins. They were interviewed twice in depth from December, 2012, to July, 2013. The findings of the study were as follows: First, as for the difficulties of their children perceived by the mothers, their children had to share everything, no matter if it was good or bad, and they were confronted with environmental constraints. In addition, they were fragile from the moment they were born. Second, concerning the self-perceived child-rearing difficulties of the mothers, they had no time to take care of themselves at all and felt lonely all the time. And they were under pressure due to financial burden. In order to help these mothers and their children to tide over their difficulties, there should be a change in the way people in general look at twins, and the establishment of emotional and financial support systems is required. The findings of the study are expected to provide some information on how to offer full-fledged support for mothers with twins.

  • This study examined the relationship between consumers' ethical ideologies and consumers' perceptions of fashion counterfeits. Forsyth's Ethics Position Questionnaire(EPQ) measuring consumers' ethical ideologies-- idealism and relativism -- was used. College students enrolled at a large university in a metropolitan area participated(N=314). There were no significant differences between counterfeit purchasers and non-purchasers on their ethical ideologies, while there were significant differences between these two groups on their perceptions toward two of the perceptions toward counterfeit factors: economic and psychological uncertainty. Idealism was not significantly related to participants' perceptions toward fashion counterfeit, while relativism was positively related only to participants' perceptions concerning the return-related uncertainty of fashion counterfeits. The results of a multiple regression revealed that consumers' economic, psychological, and return-related uncertainty were significant predictors of intent to buy counterfeit goods.

  • The purpose of this study was to investigate the relationship of depression and life-stress by values in Korean university students. Data were collected by structured questionnaires form 212 students by convenient sampling methods from August to November 2011. The type of values were classified into: personal oriented values, 64.6%; social oriented values, 35.4%. There were no significant differences in depression by values. But there were significant differences in frequency of experiences and importance of life-stress by values. Also, there were significant differences for correlation between depression and life-stress by values. These results suggest that for the university student, the nursing strategies should be developed in order to improve ability to reduce life-stress and depression considering such differences by values. Especially, it is necessary to attention in management of stress and depression for students with personal oriented values.

  • Tourism has been considered as the opposite of everyday life. Tourism has been recognized as an extraordinary experience in an extraordinary time and space, and everyday life has been related to a non-extraordinary, that is ordinary time, space, and experience. Beyond this dichotomous thought, this paper focuses on positively combining the relation between tourism and everyday life. To this end, the paper analyzed the ordinaryness of everyday life in tourist spaces, and conversely, grasped the extraordinaryness in dairy spaces. This paper shows that routines affect tourism practice, family tourism make tourist spaces domestification through performance, and the off-the-beaten track tourism spaces for experiencing the ordinary daily life of local residents are centered around the neighborhoods of global metropolises. Based on this, it was able to overcome dualism between daily life and tourism, and to promote the nexus between two.
